Noise controls at Yosemite?

One day far in the future, there might be controls on noise pollution at Yosemite. I don’t mean from kids yelling ELMER in the Pines campground, or hikers screaming for the top of Half Dome or even a rousing round of “Marco Polo” in the swimming pool.


No, more about being considerate by cars, motor homes and motorcycles on roads as they drive through the park. But let’s be honest, the emphasis is on motorcycles. Harley’s make a point of being loud. There is some truth to the logic of being heard – be seen.  I’m a soft biker myself.

The National Park Service has a group called the Natural Sounds and Night Skies Division (NSNSD) . They just finished a pilot study at Glacier National Park, Montana and at Devil’s Tower, South Dakota.

Decibels were measured and displayed on an LED sign. Brochures were passed out. Comments were solicited. They set up signs at the entrances asking vehicles to not rev engines and otherwise make their presence known “to both the animals and other visitors.

The program is just a study, but Parks can request the effort at their parks. That’s where it stands. Yosemite has a plate full of projects as well as implementing the Merced River Plan, so don’t plan on requirements for better mufflers soon.


Unrelated thought worth quoting:I have long held the opinion that the amount of noise that anyone can bear undisturbed stands in inverse proportion to his mental capacity and therefore be regarded as a pretty fair measure of it.” – Arthur Schopenhauer

    It seems clear to me that it takes after-purchase work to make a Harley sound like a hog.

    Driving style does have something to do with it, too.

    Also, I am still amazed that I encountered young men carrying a big, loud boombox on the Half Dome hike. Talk about “wilderness values.”
